Description

Technical Field

[0001] The utility model relates to the technical field of coil components, and particularly relates to a high heat-conducting coil component. Background Art

[0002] A high heat-conducting coil component refers to a coil or winding component with excellent heat-conducting performance used in electronic, electrical or mechanical equipment. These components usually need to effectively transfer heat during operation to maintain the stable operating temperature of the equipment or prevent overheating. Such coil components may use materials with high heat-conducting performance, such as copper, aluminum or other alloys with good heat-conducting performance. Their design aims to maximize heat conduction and dissipation, and they are usually used in applications that require efficient thermal management, such as electronic radiators, transformers, motor cooling systems, etc.

[0003] In the prior art, a Chinese patent with the authorization publication number CN 208479982 U discloses a coil disc component, which includes a coil disc bracket and an exciting coil disc wound by exciting wires. The exciting coil disc is divided into an inner ring part, a middle ring part and an outer ring part. The inner ring part, the middle ring part and the outer ring part are radially distributed around the center of the exciting coil disc. The top surface of the middle ring part is recessed downward so that the upper part of the exciting coil disc forms a first groove surrounding the center of the exciting coil disc, and at the same time, a first boss surrounding the center of the exciting coil disc is formed at the bottom of the exciting coil disc. Through this structure, the magnetic field distribution when the exciting coil disc is energized can be improved, avoiding the magnetic field being concentrated at a certain place above the middle ring part, making the magnetic field distribution uniform, and thus making the cookware and food heated evenly, and the heating effect of the food is better.

[0004] However, in the prior art, when fixing and installing a high heat-conducting coil, it is usually necessary to snap the spiral coil into a card slot with a shape adapted thereto. Although such installation is tight, the friction during snapping is large and the spiral structure is wound layer by layer, which easily causes difficulties in subsequent maintenance and replacement of the high heat-conducting coil. Therefore, the present application provides a high heat-conducting coil component to meet the requirements. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a high heat-conducting coil component to solve the problem that when fixing and installing a high heat-conducting coil as mentioned in the above background art, it is usually necessary to snap the spiral coil into a card slot with a shape adapted thereto. Although such installation is tight, the friction during snapping is large and the spiral structure is wound layer by layer, which easily causes difficulties in subsequent maintenance and replacement of the high heat-conducting coil.

[0006] To solve the above technical problems, the present utility model provides a highly heat-conductive coil assembly as follows, which includes a spiral coil and also includes an upper plate. A lower plate is arranged directly below the upper plate. A number of groups of sliding holes are penetrated through the surface of the upper plate, and fixing structures are arranged inside each of the number of groups of sliding holes. The fixing structure includes two symmetrically arranged vertical parts. The lower ends of the two vertical parts are fixedly connected to the surface of the lower plate. A threaded rod is fixedly connected to the central position of the upper surface of the lower plate. A threaded round seat is threadedly connected to the top of the threaded rod. A spring is arranged around the outer wall of the threaded rod. The upper end of the spring is fixed to the lower surface of the upper plate, and the lower end of the spring is fixed to the upper surface of the lower plate. The fixing structure is composed of a connected vertical part and a bent part. The bent part is located at the top of the vertical part. Circular grooves adapted to the outer diameter of the cross-section of the coil are opened on one side where two bent parts of the same group are close to each other. Inclined surfaces inclined towards the lower plate are arranged on one side where two vertical parts of the same group are far from each other. Under the elastic support of the spring, the upper plate and the lower plate move away from each other, and the inner wall of the sliding hole presses against the top of the inclined surface, causing the bottoms of the two bent parts to fit together. Moreover, the spiral coil is clamped and limited by a number of fixing structures. When the side walls of the two vertical parts are tightly clamped with the sliding holes, the two vertical parts fit together with each other, and the outer wall of the spiral coil is tightly clamped between the two vertical parts through the circular grooves. When the upper plate moves downward, the side walls of the two vertical parts gradually separate from the sliding holes, and the two vertical parts rotate in opposite directions around the bottom contact line as the axis, so that the spiral coil can smoothly pass through the circular grooves on the two vertical parts.

[0007] Preferably, a number of sector holes distributed in a circular pattern are penetrated through the surface of the upper plate, and a number of sector blocks adapted to the sector holes are arranged on the upper surface of the lower plate.

[0008] Preferably, a through hole is opened at the central position of the upper plate. The lower end of the threaded round seat is arranged in the through hole, and the upper end of the threaded round seat is movably clamped with the upper surface of the upper plate.

[0009] Preferably, a number of support legs are fixedly connected to the lower end of the lower plate.

[0010] Preferably, the outer shapes of the upper plate and the lower plate are adapted to each other.

[0011] Preferably, the heights of the central points of the upper plate and the lower plate are both lower than the heights of the surrounding circular edges, and the shapes are arc-shaped.

[0012] Preferably, the height of the fixing structure far from the axis of the lower plate is higher than the height of the fixing structure close to the axis of the lower plate.

[0013] Preferably, a circular chamfer is arranged at the upper end of the threaded round seat.

[0014] Technical solution:

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above solution, by rotating the threaded round seat, the threaded round seat spirally descends along the thread direction of the threaded rod. At this time, the spring is compressed and deformed under the combined action of the upper plate and the lower plate, which is convenient for resetting the upper plate during installation. When the threaded round seat descends, the lower end presses the middle part of the upper plate to descend. At the same time, the peripheral edge of the upper plate is assisted by both hands until the fan-shaped hole and the fan-shaped block are mutually engaged. At this time, the upper parts of multiple groups of fixing structures are separated from the sliding holes, and the sides of the two inclined surfaces are separated from the sliding holes. Because the bending part is in the shape of wider at the top and narrower at the bottom, when the vertical part passes through the sliding hole, the two groups of vertical parts can move in the sliding hole, and then the bending part can be slightly separated, making the gap between the two groups of circular grooves larger, so that the spiral coil can pass through the circular groove smoothly, and the disassembly operation of the spiral coil can be completed smoothly without damaging the spiral coil, which is convenient and fast.

[0028] Such as Figures 1-4As shown, an embodiment of the utility model provides a high thermal conductivity coil assembly, including a spiral coil 7, and also including an upper plate 1, a lower plate 2 is arranged directly below the upper plate 1, a plurality of groups of sliding holes 4 are opened through the surface of the upper plate 1, and a fixing structure 6 is arranged inside the plurality of groups of sliding holes 4, and the fixing structure 6 includes two groups of symmetrically arranged vertical portions 61, and the lower ends of the two groups of vertical portions 61 are fixedly connected to the surface of the lower plate 2, a threaded rod 10 is fixedly connected to the center position of the upper surface of the lower plate 2, and the top of the threaded rod 10 is threadedly connected to a threaded round seat 9, and a spring 11 is arranged around the outer wall of the threaded rod 10, and the upper end of the spring 11 is fixed to the lower surface of the upper plate 1, and the spring 11 The lower end of the fixing structure 6 is fixed to the upper surface of the lower plate 2, and the fixing structure 6 is composed of a vertical portion 61 and a curved portion 62 connected to each other. The curved portion 62 is located at the top of the vertical portion 61. A circular groove 64 adapted to the outer diameter of the coil cross section is provided on the side where the two curved portions 62 of the same group are close to each other, and an inclined surface 63 inclined toward the lower plate 2 is provided on the side where the two vertical portions 61 of the same group are away from each other. Under the elastic support of the spring 11, the upper plate 1 and the lower plate 2 are away from each other, and the inner wall of the sliding hole 4 squeezes the top of the inclined surface 63, so that the bottoms of the two curved portions 62 fit each other, and the spiral coil 7 is limited by being engaged with a number of fixing structures 6, and the side walls of the two groups of vertical portions 61 and the sliding holes are connected. When the two sets of vertical parts 61 of the elastic extrusion parts are tightly connected, the outer wall of the spiral coil 7 is tightly connected between the two sets of vertical parts 61 through the circular groove 64. When the upper plate 1 moves downward, the side walls of the two sets of vertical parts 61 gradually separate from the sliding hole 4, and the two sets of vertical parts 61 rotate in opposite directions with the bottom contact line as the axis, so that the spiral coil 7 can smoothly pass through the circular groove 64 on the two sets of vertical parts 61. By rotating the threaded round seat 9, the threaded round seat 9 is spirally lowered along the thread direction of the threaded rod 10. At this time, the spring 11 is squeezed and compressed by the cooperation of the upper plate 1 and the lower plate 2, which is convenient for resetting the upper plate 1 during installation, and the threaded round seat 9 is downward. At the same time, the lower end squeezes the middle part of the upper plate 1 to descend, and at the same time, the circumferential edge of the upper plate 1 is assisted by both hands until the fan-shaped hole 3 and the fan-shaped block 8 are engaged with each other. At this time, the upper part of the multiple groups of fixing structures 6 are separated from the sliding hole 4, and the side surfaces of the two inclined surfaces 63 are separated from the sliding hole 4. Because the curved portion 62 is wide at the top and narrow at the bottom, when the vertical portion 61 passes through the sliding hole 4, the two groups of vertical portions 61 can move in the sliding hole 4, and then the curved portion 62 can be slightly separated, so that the gap between the two groups of circular grooves 64 becomes larger, so that the spiral coil 7 can pass through the circular groove 64 smoothly, and the removal operation of the spiral coil 7 can be completed smoothly without damaging the spiral coil 7, which is convenient and quick.

[0029] like Figures 1-4As shown, in this embodiment, a plurality of sector holes 3 distributed in a circular pattern penetrate through the surface of the upper plate 1. A plurality of sector-shaped clamping blocks 8 adapted to the sector holes 3 are provided on the upper surface of the lower plate 2. A through hole is provided at the central position of the upper plate 1. The lower end of the threaded circular seat 9 is arranged in the through hole, and the upper end of the threaded circular seat 9 is movably clamped with the upper surface of the upper plate 1. A plurality of support legs 5 are fixedly connected to the lower end of the lower plate 2. The outer shapes of the upper plate 1 and the lower plate 2 are adapted to each other. The heights of the central points of the upper plate 1 and the lower plate 2 are lower than the heights of the surrounding circular edges and the shapes are arc-shaped. The height of the fixing structure 6 far from the axis of the lower plate 2 is higher than the height of the fixing structure 6 close to the axis of the lower plate 2. The upper end of the threaded circular seat 9 is provided with a circular chamfer. The shape of the upper plate 1 is arc-shaped and the central position is lower than the center of the circle, which can increase the heat dissipation area of the spiral coil 7. And the eight groups of sector holes 3 opened at the upper end can facilitate the ventilation and heat dissipation of the spiral coil 7, playing a protective role for the spiral coil 7. The mutual clamping of the sector holes 3 and the sector-shaped clamping blocks 8 can facilitate the positioning of the vertical movement of the upper plate 1 and the lower plate 2, preventing movement deviation and having an adverse impact on the disassembly operation of the spiral coil 7.

[0030] For the technical solution provided by the present utility model, when it is necessary to disassemble the spiral coil 7 from the upper plate 1 for maintenance, first rotate the threaded circular seat 9 so that the threaded circular seat 9 spirally descends along the thread direction of the threaded rod 10. At this time, the spring 11 is compressed and deformed under the combined action of the upper plate 1 and the lower plate 2, which is convenient for resetting the upper plate 1 during installation. And when the threaded circular seat 9 moves downward, the lower end presses the middle part of the upper plate 1 to descend. At the same time, assist the circular edge of the upper plate 1 with both hands until the sector holes 3 are mutually clamped with the sector-shaped clamping blocks 8. At this time, the upper parts of the multi-group fixing structures 6 are separated from the sliding holes 4, and the sides of the two inclined surfaces 63 are separated from the sliding holes 4. Because the bending part 62 is in the shape of wider at the top and narrower at the bottom, when the vertical part 61 passes through the sliding hole 4, the two groups of vertical parts 61 can move in the sliding hole 4. Furthermore, the bending part 62 can be slightly separated, making the gap between the two groups of circular grooves 64 larger. Then the spiral coil 7 can smoothly pass through the circular grooves 64, and the disassembly operation of the spiral coil 7 can be successfully completed without damaging the spiral coil 7, which is convenient and fast.

[0031] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can also fully understand the present utility model without the description of these details.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
